If you are planning to see wildlife, please follow the latest government advice regarding coronavirus, and bear in mind that there are different restrictions in place between England, Wales, Scotland and Northern Ireland.
Brilliant purple carpets of bluebells are one of the most stunning spectacles in spring. There are two species of bluebell found in the UK; the native species called the common bluebell (Hyancinthoides non-scripta), and a non-native introduced species called the Spanish bluebell (Hyactinthoides hispanica).
The common bluebell is also known as the English or British bluebell, and sometimes referred to as the native bluebell. In Scotland, it is often called the wild hyacinth and the ‘bluebell’ is actually used for the harebell (Campanula rotundifolia). The common bluebell is protected under the Wildlife and Countryside Act 1981, and must not be picked or uprooted. Care should be taken when going to see bluebells to ensure that they, and other species, are not trampled.
As the name suggests, the Spanish bluebell is native to Spain, and to Portugal. It was introduced as an ornamental plant in British gardens around 1680, and was first recorded in the wild in 1909. It is now considered a naturalised species.
The genus name Hyancinthoides comes from Greek mythology. Prince Hyacinthus (sometimes Prince Hyacinth) was a Spartan prince and the lover of Apollo. He was accidentally killed when Apollo was teaching him to play quoit. As Apollo cried over the body of his dying lover, his tears (or the blood of Hyacinth himself) created the hyacinth flower, marked with ‘alas’ on its petals.
The two species can be told apart, however they can hybridise and the hybrid (Hyancinthoides x massartiana [hispanica x non-scripta]) can have features from both, making identification tricky. The hybrid is also known as the garden bluebell, and was first recorded in the wild in 1963.
Both the Spanish and the hybrid bluebell are more vigorous than the native species (meaning that they outcompete the common bluebell for resources such as light and space), and conservationists are worried that continued hybridisation may mean we lose the unique characteristics of the common bluebell. A study by Plantlife found that one in six broadleaved woodlands contained the hybrid and/or the Spanish bluebell.
Where are bluebells found?
Common bluebells can be found from northwest Spain and through to the Netherlands in continental Europe. It is thought that the British Isles may have half of the species’ global population.
Common bluebells are typically associated with ancient deciduous woodlands (continuous tree cover since at least 1600 in England and Wales, 1750 in Scotland), and other ancient woodland indicator flowers include wood anemone, wood sorrel and ransoms. These are species that typically spread slowly, and usually require long-term and stable woodland cover to survive. Bluebells can spread via seed, but their bulbs can also split to form clones.
However, common bluebells can be found elsewhere if the soil is damp and rich – including hedges, open hillsides, sea cliffs, and even some islands, such as Skomer. They can be planted in gardens, if you are planning to do so, check that a) the bulbs you are being sold do actually belong to the common bluebell species and not the hybrid or Spanish species, and b) that the commercial grower has a licence to source and grow common bluebells from the UK.
Hybrid and Spanish bluebells can be found in gardens, woodlands, churchyards, and rough ground. If you are removing hybrid or Spanish bluebells from your garden or land (remember that it’s only legal to dig up wild plants on your own land), it’s best to dispose of cuttings and bulbs carefully. Composting bulbs before they are dead can lead them to propagate.
When do bluebells bloom?
The common bluebell flowers in April and May. By flowering early in spring, it is able to take advantage of the spring sunlight filtering down to the woodland floor, before the canopy above becomes too dense. According to data from the Nature’s Calendar survey, the first flowering of bluebells has advanced by at least 17 days since 2001.
How to tell the difference between common and Spanish bluebells
There are a number of key identification features to look out for when trying to identify bluebells: colour of the petals and of the pollen, shape of the inflorescence (the flowers and top of the stem), and of the flowers, and presence or absence of scent.
However, as mentioned in the introduction, it’s worth remembering that the two species can hybridise and hybrids can have features from both species.
Identifying the common bluebell (Hyancinthoides non-scripta)
- Petal colour: deep violet-blue
- Pollen colour: cream
- Shape of inflorescence: flowers and stem droop or nod, with flowers all on one side
- Shape of flowers: flowers appear tubular, and the tips of the petals are reflexed (curved back)
- Scent: strong, sweet scent
Identifying the Spanish bluebell (Hyancinthoides hispanica)
- Petal colour: varied colours including pale blue, white, and pink
- Pollen colour: blue or green
- Shape of inflorescence: erect, without drooping, with flowers not restricted to one side
- Shape of flowers: flowers are more saucer-shaped than tubular, and the tips of the petals are not so reflexed (curved back)
- Scent: very little or no scent
Does any wildlife feed on bluebells?
Bluebell flowers are attractive to pollinating insects, including butterflies and bees. The bulbs can be eaten by wild boar, which are omnivorous and are known to eat roughly 400 different species of plants and animals. There have been limited studies to the relationship between bluebells and the rooting of wild boar.
